SIGNAL-LAMP.

Specification of Letters Patent.

Patented Apr. 29, 1919.

To all whom it may concern:

Be it known that we, OnARLEs E. ARCHER and EDWARD C. HUMPI-IREYS, citizens of the United States of America, residing at Deunit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Signal-Lamps, of which the following is a specification, reference being had therein to the accompanying drawings.

In our companion application, filed under even date, there is disclosed a signal lamp embodying an adjustable yoke, an adjustable lamp in the yoke, and means for independently adjusting said lamp and said yoke, said means being operatable by one hand in proximity to the lamp.

The object of our present invention is to provide a lamp of the above type with controlling or actuating means that may be located at a point remote from the lamp thus permitting of the lamp being placed on a plane or the forward end of the fuselage of an air-plane, on the bow of a motor boat, or on the forward end of a vehicle, and controlled and actuated from the seatof the aviator, motorman or chaufi'eur.

A further object of our invention is to provide a lamp of the above type wherein the adjusting or controlling mechanism is compactly assembled, positive in its operation, and free from injury under ordinary circumstances.

The above and other objects are attained by a mechanical construction that will be hereinafter specifically described and then claimed, and reference will now be had to the drawing wherein Figure 1 is a rear elevation of the signal lamp, partly broken away and partly in section;

Fig. 2 is a front elevation of a control board;

Fig. 3 is a side elevation of the same partly broken away and partly in section;

Fig. 4 is a side elevation of a portion of the signal lamp;

Fig. 5 is a horizontal sectional view taken on the line VV of Fig. 1; a

Fig. 6 is a plan of a portion of the lamp on the line VIVI of Fig. 1, and

Fig. 7 is a horizontal sectional view taken on thee-line VII-VII of Fig, 1. I

To put our invention into practice, we provide a hollow pedestal 1 that may be seecured to a suitable base, and said hollow pedestal hastwo compartments 2 and 3 separated by a par titiona affording a bearing 5 for a tubular vertically disposed yoke shaft "6. v p

Rotatabl'e the upper. end of the pedestal 1 and extending into the compartment 3 thereof is a hollow yoke head 7 having sets of yoke arms 8 and 9 to which areconnected opposed adjustable casings 10 and 11 re spectively. The casings 10 and 11 support the trunnions or gudgeon's 13 of a lamp housing 14- containing an electric incandescent lanip 15.

The yoke head. 7 is integral or fixed relatiVe. to the tubular shaft 6, so that when said shaft is rotated in the bearing 5, the oke and lamp are turned about the axis 0 the pedestal 1. To accomplish this, a worm gear 16 is mountedon the lower end of the tubular yoke shaft 6 and meshing with said worm gear is a worm 17 rotatably supported in the compartment 2 of the pedestal by suitable bearings 18 and adapted to have movement imparted thereto by a flexible shaft 19 extending into the pedestal.

J ournaled in the tubular yoke shaft 6 is a lamp actuating shaft 20 that has the upper end thereof extending into the yoke head 7 and provided with a wheel 21. Trained about this wheel is a flexible power transmission member 22 that extends through the set of yoke arms 9 and is trained on a wheel 23 in the casing 11 and fixed relative to the trunnion or gudgeon 13 of the lamp housing 14.

Fixed on the lower end of the lamp actuating shaft 20, below the Worm gear 16, is a spiral gear 24 meshing with a worm 25 supported within the compartment 2 of the pedestal 1 and adapted to have movement imparted thereto by a flexible shaft 26 extending into said pedestal.

The flexible shafts 19 and 26 extend to a control board 27 having enlargements 28 provided with a series of circumferentially disposed openings or notches 29. The ends of the flexible shafts 1'9 and 26 are provided with cranks 30 having the outer ends thereof equipped with spring pressed plungers 31 adapted to engage in the openings or notches 29 and hold the cranks 30 in adjusted position. It is therefore possible to adjust either one of the cranks 30 and set the yoke at a. desired angle, also the lamp housing 19. Furthermore, it is possible to oscillate or wigwag either the yoke or the lamp, and the enlargements 28 may he compartment 3 of the pedestal 1 and the brushes 37 insure proper electrical connection irrespective of Whether the yoke is turned about its axis or not.

It is obvious that the flexible shafts 19 and 26 may be of any desired length so that the signal lamp may be easily operated at a point remote from its location.

What We claim is:

A signal lamp comprising a pedestal, an

adjustable yoke rotatable on said pedestal, a lamp trunnioned in said yoke, vertically disposed concentric shafts in said pedestal adapted for independently imparting movement to said yoke and said lamp, superposed gears on the lower ends of said shafts, horizontal worms in said pedestal at oppositesides of said shafts and meshing With said gears, a control board at a point remote from said pedestal, flexible shafts extending from said control board into said pedestal and adapted for imparting movement to said Worms, and means on said control board for holding said shafts'in adjusted positions.

In testimony whereof We aflix our signatures in presence of two Witnesses.
